NO BRAKE LIGHTS?  Never thought of that - wonder how many get to retire early 
because of "rear end accidents"?

Picture this - stand-up comic Steven Wright has a monolog - - -"I wired my 
accelerator to my break lights - when someone is following too closely I punch 
it and disappear - they wonder what happened . . ."

Cheers

I wouldn't call it severe.  Think of the throttle (rheostat?) as having a 
neutral position, which is part way down.  Push further, it accelerates.  More 
push, more acceleration.  Lift throttle is similar.
Lift a little, gradual decel, etc.

As for the brake light issue, my recent Thanksgiving trip to Portland gave me 
the opposite problem.  I was in stop and go congestion on I-5.
I'd lift to slow, but because the brake lights don't come on, cars behind me 
had no idea that I had started slowing until it became very obvious.  Given the 
congestion and that people tend to follow way too close, I thought this could 
be dangerous, so I "shifted" into regular "drive" (simulating a gas car with an 
auto trans) which forced me to use the brake pedal to slow even slightly.  Thus 
lighting up the brake lights and warning people behind me.

Hans.
